Teaching at the Right Level (TaRL) is an evidence-backed educational approach that helps children develop basic reading and mathematics skills, opening doors to a brighter future. It is an approach developed by the Indian NGO Pratham that aims to build foundational skills in math and reading for all children before exiting the primary school. At the instructional level, the approach works by assessing childrens learning levels using a simple tool; grouping children based on learning levels rather than age or grade; using a range of engaging teaching and learning activities, and focusing on foundational skills rather than solely on the curriculum, and tracking childrens progress. A series of randomized evaluations over the past fifteen years have shown that TaRL consistently improves learning outcomes when implemented well and has led to some of the largest learning gains among rigorously evaluated education programs. The program is scaled up in several countries in South-Asia and Sub-Saharan Africa. It is first piloted at a relatively small scale, and strong M&E helps inform necessary adaptations before it moves to scale. In some countries, it has scaled to reach several millions of children."
